Fi Smart Dog Collar ReviewThere’s no worse feeling in the world than when your dog has gone missing.

The American Humane Association estimates that approximately 10 million pets are lost in the United States each year.

Whether your dog wandered off, snuck out the back gate, or ran out of the front door, the anxious twisting in your stomach is the same.

If your dog tends to run off, or you want to be proactive if it ever happens, a dog tracker can be key in quickly locating your dog.

In this blog post, we provide our Fi Smart Dog Collar review for their newly improved Series 2 version.

What is the Fi Smart Dog Collar?

The Fi Smart Dog Collar essentially is a GPS tracking collar meant to quickly locate your dog in case they get lost.

With this device, you can track your dog’s location right on your phone using their app. It even activates an LED flashing light on the dog collar itself.

With the latest Series 2 version, the Fi Smart Dog Collar has even more great features, which we discuss in this blog post.

Key Benefits of the Fi Smart Dog Collar Series 2

1. GPS Tracking + Lost Dog Mode

When you receive your shipment from Fi, you register the collar with a Fi account through their app. Once the collar is connected, the app will show you your dog’s location – whether they’re at home or elsewhere.

Lost Dog Mode will show you your dog’s location on the Fi app, but it will also trigger an LED light on the Fi collar. The light will flash red as long as Lost Dog Mode is activated, which makes it easier to spot your pup from a distance.

Between the GPS tracking and the flashing red light, finding your lost dog will be much easier than just taking a wild guess of which direction he ran.

2. Geofence Perimeter With Immediate Alerts

With the accurate GPS tracking of the Fi Smart Dog Collar comes a few cool features. For instance, you can set a geofence around your yard for your sneaky little escape artist.

As soon as your dog crosses that invisible fence line, the app will send you an alert so you can start tracking them down immediately, rather than hours later when you notice they aren’t in the yard anymore.

3. Dog Walker Monitor

Your designated humans will need to download the Fi app themselves before they take your dog beyond the geofence area. Once they do, you will receive an alert on your phone that says your dog has just left with that designated human, so you can keep track of who has your dog out and when.

If someone takes your dog beyond the geofence and they are not registered as a designated human on your account, the Fi app will alert you that your dog has left home.

This “dog walker monitor” feature helps you stay informed in real-time about when your dog leaves home, who they are with, and where they go on that walk.

This is perfect for peace of mind when you’re traveling without your dog or keeping an eye on your dog walker.

4. Monitor Fitness Activity By Tracking Steps

The Fi Smart Dog Collar tracks your dog’s location, but it also tracks the number of steps your dog takes.

The collar acts as a pedometer and sends the step count to your Fi app each day. The default steps goal is 10,000 steps per day, but you can easily adjust that number based on your dog’s needs.

Not only can you use this feature to track your dog’s steps, but you can also compare their average step count to other dogs of the same breed.

The number of steps from other Fi collar users in the U.S. appears in a feed, similar to a social media feed, where you can see how your dog’s activity compares to others.

The comparison may be a great reminder that you need to take your dog out for more exercise or that you may be working him a bit too much!

5. Access to Fi Community

The Fi app is an excellent way to track your dog’s fitness, but it’s also a great way to meet other Fi users in your area. You can connect your Fi app to your Instagram account to share photos with other Fi users and connect with other owners nearby.

Additionally, the Fi app will show you dogs in your neighborhood to meet some potential playmates.

Improvements from Series 1 to Series 2

The Fi product development team heard several gripes about the first model, and they took them to heart.

They made improvements, beefed up the specs, and recently released the Fi Smart Dog Collar Series 2 to replace the first model entirely. To state outright, they no longer manufacture the first series of Fi dog collars, only the Series 2.

The Series 2 improvements include reinforced hardware so the collar can withstand up to 300 pounds of pull force. No matter how much your dog tugs at the lead, the Fi collar will not break. It is waterproof and dirt-proof, so it’s built to last both indoors and outdoors.

One of the primary complaints from the first series of collars was that the aluminum faceplate fell off or cracked easily, so Fi made sure that the Series 2 faceplate was much more durable.

The Series 2 also has a whopping 400% improvement in its antenna signal sensitivity, so the network connection is much more reliable now. If your dog runs off  in the middle of the woods, you’ll still likely be able to pinpoint his location with the Fi app.

Perhaps one of the most significant improvements with the Series 2 is the Wi-Fi integration. Since the collar connects directly to your home’s Wi-Fi network, its escape detection is much more accurate (and fast) than the first series of collars, so you will know the very second your dog leaves the geofence area.

The Wi-Fi integration also helps the battery life last much longer than it used to: up to three months once fully charged. The first model was lucky to survive more than a few days with a full charge!

What Customers Are Saying About the Fi Smart Dog Collar Series 2

Man listening to customer on the phoneWhile dog parents weren’t so wild about the first series of Fi Dog Collars, Series 2 made some waves. The reviews on Chewy say that the collar has been a fantastic addition to many dog care routines, and owners are loving the peace of mind.

One reviewer posted that his fur baby had developed a habit of wandering off to explore their neighbors’ yards. They tested out the Series 2 and tracked her down within minutes! They claimed to previously spend half an hour wandering around yards to try to find her.

Another Fi fan said that the collar helps her feel so much better about her Golden Retriever puppy going on walks with a dog walker. She can see her dog’s exact walk path and how far they went.

Some Drawbacks of the Fi Smart Dog Collar Series 2

There are plenty of good things about the Fi Smart Dog Collar Series 2, but there are some “drawbacks” to consider before you make your final purchase.

First and foremost, the GPS tracking feature requires an annual subscription if you want to take full advantage of it.

If you do not purchase the yearly subscription, you can still track your dog as long as he is within range of your Wi-Fi network or your phone with the Fi app, but not when he bolts from the yard. You will not be able to use Lost Dog Mode without a subscription either.

The cost of this subscription is $99 a year, or about $8.25 per month – a small price to pay for the security of knowing your pup’s whereabouts at all times.

Secondly, some users say that the Fi app is a bit too simple or clunky for the price you’re paying for the collar and subscription.

Others have said that the simple app design is a good thing since it’s easy to navigate through the different features that Fi provides.

Fi makes an effort to improve their app and the features that come with it, so it is likely that future updates will be released and bring even more value to the app. All while making sure your dog stays safely close to home.

Conclusion for Fi Smart Dog Collar Review

The Fi Smart Dog Collar is a high quality dog tracker with great reviews, especially for its new Series 2 version.

Some of its key features include GPS tracking, lost dog mode, a geofence perimeter, a dog walker monitor, fitness tracking, and access to the Fi community.

Fi has greatly improved its dog collar with its Series 2 version. It has the ability to withstand 300 pounds of pull force, has a more durable faceplate, offers 400% improvement in its antenna signal sensitivity, has Wi-Fi integration, and has a longer battery life.

If you don’t mind paying for a subscription (which most GPS trackers require), this is well worth the peace of mind in case your dog gets lost.

    If my dog got lost out in the country in farm land would I be able to find her.How many miles will it cover if she is lost for a long time or don’t know what way did she go.

    We live in a very wooded area. Several years ago, our old dog wandered off, never to be found, on the night of the first snowstorm of the year. I’d have paid anything to have him back. Our new girl is chipped, but if nobody finds her, or doesn’t think to check for it, we might never find her either, if she finds a way to get to that squirrel on the other side of the fence and takes off. The Fi collar and service are worth every single penny if just for peace of mind!
